A waste stripping unit in a packaging production machine (), positioned downstream of a cutting unit (). The stripping unit includes a frame and two rotary tools cooperating with one another (). A first tool has waste stripping needles protruding radially outward from the outer surface. The two tools () are mounted in a removable cassette (). A frame () is provided with bearings supporting the two tools (), and which can be introduced into, attached to and extracted from the frame ().

Waste stripping unit with simplified tool adjustment in a packaging production machine

A transfer device for one or more flat substrates (), which can be inserted between two successive units upstream and downstream () in a packaging production machine (), the device including a bridge () with an upper surface () providing a junction between the upstream unit () and the downstream unit (). An adjustment device () varies a length (L, L) of the bridge (). The bridge () is a static apron on which the substrate () slides, having a fixed transversal end () and a mobile transversal end (). The adjustment device () varies a position of the mobile end (), as a function of a spacing (E, E) between the two units.

Transfer device for flat substrate in a packaging production machine

A waste stripping unit in a packaging production machine (), positioned downstream of a cutting unit () for cutting one or more flat substrates (). The stripping unit includes a frame () supporting two rotary tools cooperating with one another (). At least one of the two tools () is formed with a mandrel () and a removable sleeve (), and the sleeve can be inserted on, fixed to and driven in rotation by the mandrel (). One tool has protruding needles for the stripping and the other tool has a flexible strip cooperating with the needles.

Waste stripping unit with simplified tool change for a packaging production machine

A device for positioning and assembling successive frames in a machine of a production line. The device is intended in particular for relative positioning of two adjacent frames, namely an upstream frame and a downstream frame. At least one link connects the upstream frame to the downstream frame and supports the upstream part of the downstream frame. The link comprises a cylinder that extends across the successive frames and is received in a bearing at each of the adjacent frames. A tightenable tension rod locks the selected relative positions of the successive frames.
